After you install the licensing components, you are ready to obtain your license files from citrix.com. At citrix.com (or My Account), you generate a license file and download it to the license server. Then you must import the license files through the License Administration Console.
Before going to the Citrix Web site, you need the following information at hand:
You can find the license server host name and Ethernet address in the License Administration Console in the Administration area on the System Information tab. You can also run the hostname command at a command prompt on the license server.
For License Server VPX and remote systems: Open a web browser and go to http://License Server Name:webport.
Users can begin using these licenses as soon as the licenses are read by the license server.
and type the following command: lmreread -c @localhost -all.
